Reference #44: An Elegant Puzzle
Consider two types of goals: investments and baselines. Investments describe a future state you want to reach. Benchmarks describe parts of the present system you'd like to preserve.
You should consider pairing investment goals with baseline goals; doing so constrains the solution space. This allows you to be clear on the trade-offs you're comfortable with.
